A short grass variety often used on golf courses, Scott's creeping bentgrass is genetically engineered to resist sprayings of glyphosate. In 2005, Scott conducted field trials of bentgrass in Idaho; five years later the GMO plant was found growing in Oregon even though it was never deregulated. Possibly because they are small seeds that are easily transferred by wind and pollen, GMO creeping bentgrass remains in USDA regulatory limbo.
